PPT-Chapter 27 Interference and the Wave Nature of Light

Dr Quantum 271 The Principle of Linear Superposition When two or more light waves pass through a given point their electric fields combine according to the principle of superposition The waves emitted by the sources start out in phase and arrive at . Has wave properties.. Can diffract.. Can constructively or destructively interfere. .. Coherent Light. A beam of light that has the same frequency, wavelength, phase, and direction is called . coherent. May . 21, . 11.30am -1.30pm, here, cumulative.

T. ypes of wave interactions. Reflection. Refraction. Diffraction. Interference. Reflection. The bouncing back of a wave when it hits a surface.. * NOTE: When waves hits a substance some of it is transmitted and some of it is reflected.. REFLECTION. Reflection. is where a wave strikes an object and bounces off.. When a wave strikes a flat reflective surface it will reflect back at the same angle at which it struck the surface. This is called the Law of Reflection.. Electromagnetic Spectrum and Spectroscopy. 0. Innovators Presentations. Pictures from Week 3 Conservatory Field . Trip. Questions from reading assignments?. Light moves at light speed. Wave Properties of Light. Physics . 2212. Light. Light has Wave properties. Light can Diffract. Light can Interfere. Constructively. Destructively. Wave Fronts. Lines that are perpendicular to the motion of the wave, indicate the location of the crests in the waves that are traveling together.. Associate Professor in Physics. Post Graduate Govt.
